TAKE-UP FOR BEARINGS.

Application led August 5, 1926. Serial No. 127,430.

This invention aimsto provide novel means for taking up the wear in bearings, and more particularly in bearings which support the rolls of metal working machines.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present appertains. v

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be `made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in side elevation, a. rolling machine equipped with the device forming the subject matter of this application;

Figure 2 is a section taken about on the line 2-2 of Figure 1, parts remaining in elevation;

Figure 3 is a detail enlarged from Figure 2, the constituent members of the take-up having been shifted from the positions which they occupy in Figure 2; `and Figure 4 is a composite perspective View showing the members of the take-up mechanism.

The device forming the subject matter of this application may be embodied in machinos of widely different sorts, but, by way of illustration, there is shown in the drawV ings, a rolling machine comprising a frame l embodying standards 2 having longitudinal openings 3, there being guideway-s 4lon the inner sides of the standards 27 along the longitudinal edges of the openings 3. Bearings 5, or brasses are located in the openings 3 at theL lower end thereof, and have extensions 6 received in the guideways 4 to prevent the bearings from moving outwardl'. jburnaled on the bearings 5, and the bearings 5 are prevented from movingl inwardly by engagement with the end of the roll 8. The roll 8 is in cooperation with an upper roll 9 the trunnions 10 of which are engaged by bearings 11I held downby compression springs 12 cooperating with followers 14, the followers being fed downwardly by compression screws 15 or the like, the screws be- The trunnions 7 of a lower roller 8 arev ing threaded intothe upper end of the standards 2.' f

The construction above described is common, and no novelty is claimed for it, saving in so far as it may enter into patentable combinations with parts hereinafter de` scribed.

lt happensA very often that the bearings 5 do not wear evenly.. Thusnthe bearings 5 may Wear down from the dash line 16 of Figure 3 to the solid line 17 of that figure, the bearing 5 then assuming, in section, the form of a blunted wedge.y The' object of lthis invention is to provide novel means for taking up wear of the kind last above alluded to.

in carrying out the invention, there is provided a metal member 18, in the form of a plate,the upper surface of the member 18 being fiat, as shown at 19, and the member 18 being provided at its ends Wit-l1 oonvexed lower surfaces 20. In the lower surface of the plate 18 there is a recess 21 havi ing a convened surface 22. The surfaces 20 and 22 kare concentric, and, preferably, are

parts of circles having a very long radius.

At one end, the member 18 has lateral project-ions 27.y rlhere is provided, as a part of the take-up mechanism, a member or plate 23 which is complemental to the member or plate 18. The member 23 has a iiat lower surface 28. The member 23 is provided at its edges with concaved surfaces 241 and has, intermediate its ends, an upstanding yrib 25 the upper surface ofv which is concaved `as at 26. The radius'of curvature of the surfaces 24,- preferably s about the same asthe radius of curvature of the surfaces 20, and the radius of curvature of the surface 26 is about the same as the radius of curvature of the surface shown at 22.

The flat lower surface 28 of` the member 23 rests on the surface 29 of the standard 2 which exists at the lower end of the opening 3. The fiat surface 19 of the member 18 rests against the lower surface 30 of the bearing V5. The rib 25 is received in the recess 21, the recess being` somewhat Wider thanL the rib, the concaved surface 26 of the rib engaging the conveXed surface 22 of the recess, and the conveXed `surfaces 20 of the member 18 engaging the concaved Surfaces 2l1'o'f 'the member 23. The projections 27 on the member 18 are received in the guide- Ways fof the frame 1v and the member l18 cannot shift out o place horizontally, ulthough it can have some vertical movement, :ind .1 little tiltingI,r movement with respect. to the horizonzil, as well.

from the As the bearing 5 wears away line shown :it 17, the bearing .5 of course f' machine is in use, the men'iher 23 will move endwiee, the conceived Surfaces of the 1nem ber 23 cooperating with the conveXed surfacw ol' the member 1S, to take up weer, it being reculled that when the benring 5 is tilted vertically, :is it wearsy away, the member 18 is tilted nreordingly, find. thus, is mede ellieient :is n menne whereby the jar or vihrntion muy he trnnsu'iitted to the plate 23, to enlise the plate E23 to move endwise und take up the wear, :1S aforesaid. Although the member 23 can move relatively to the member 18, that movement occurs within limits, defined by the amount that the rib 25 can move in the recess 21.

lVhnt is claimed ish* A take-up for bearings, comprising :L pair olf' superposed plate-like members, one of Suid membere` being provided on its inner surface with :1 recess which extends but purtwziy through that member, the other member having a rib, received in the recess, the re cess beirut;r lnrge enough so that the rib may have limited movement therein, the said ruemherri having contacting surfaces on opiosite sides; of the rib und the f'roove the rib and the groove having eo1'1tin,,tingr Surfaces, :d1 ol said surfaces on one of Said members being,r correspondinggly muttered, und all of .Quid sur'lnces ou the other of said members being coneiived to fit upon the cou- JOHN A.
